@aws-sdk/util-hex-encoding

What is @aws-sdk/util-hex-encoding?

@aws-sdk/util-hex-encoding is a utility package from AWS SDK for JavaScript that provides functions to encode and decode hexadecimal strings. This can be particularly useful for handling binary data in a readable format.

What are @aws-sdk/util-hex-encoding's main functionalities?

Hex Encoding

This feature allows you to convert a Buffer or Uint8Array to a hexadecimal string. The code sample demonstrates encoding the string 'Hello, World!' into its hexadecimal representation.

const { toHex } = require('@aws-sdk/util-hex-encoding');
const buffer = Buffer.from('Hello, World!');
const hexString = toHex(buffer);
console.log(hexString); // Outputs: 48656c6c6f2c20576f726c6421

Hex Decoding

This feature allows you to convert a hexadecimal string back into a Buffer. The code sample demonstrates decoding the hexadecimal string back into the original 'Hello, World!' string.

const { fromHex } = require('@aws-sdk/util-hex-encoding');
const hexString = '48656c6c6f2c20576f726c6421';
const buffer = fromHex(hexString);
console.log(buffer.toString()); // Outputs: Hello, World!
